    Abstract Background: Cardiac adverse events (AEs) are common in tyrosine kinase inhibitors(TKIs). This study explored the cardiac AEs of TKIs through the Food and Drug Administration's Adverse Event Reporting System (FAERS).
    Methods: Disproportionality analysis and Bayesian analysis were utilized for data mining of the suspected cardiac AEs of TKIs, based on FAERS data from January 2004 to December 2021.
    Results: A total of 4708 cardiac AEs reports of sorafenib, regorafenib, lenvatinib, and cabozantinib were identified. Hypertension accounts for the most reported cardiac AE. Lenvatinib appears to induce cardiac failure with the highest signals strength [ROR = 7.7 (3.46,17.17)]. Acute myocardial infarction was detected in lenvatinib [ROR = 7.91 (5.64,11.09)] and sorafenib [ROR = 2.22 (1.74, 2.84)]. Acute coronary syndrome was detected in lenvatinib [ROR = 11.57 (6.84, 19.58)] and sorafenib [ROR = 2.81 (1.87,4.24)]. Atrial fibrillation was detected in sorafenib [ROR = 1.82 (1.55,2.14)] and regorafenib [ROR = 1.36 (1.03,1.81)]. Meanwhile, aortic dissections were detected in sorafenib [ROR = 5.08 (3.31,7.8)] and regorafenib [ROR = 3.39 (1.52,7.56)]. Most patients developed hypertension and cardiac failure within 30 days of initiating TKI treatments. Patients taking lenvatinib had an increased incidence of developing acute coronary syndrome after 180 days of treatment.
    Conclusion: Analysis of FAERS data provides a precise profile on the characteristics of cardiac AEs associated with different TKI regimens. Distinct monitoring and appropriate management are needed in the care of TKI recipients.

    Abstract Objective: To explore the synergistic anti-tumor mechanism of astragalus polysaccharids(APS) combined with doxorubicin in HL-60/A cells.
    Methods: The phenotype of HL-60/A was identified by using RT-PCR, Wester blot and CCK-8, the antitumor effect of astragalus polysaccharids combined with doxorubicin on HL-60/A cells was detected by CCK-8, the apoptosis of HL-60/A after treating with different drugs was detected by Annexin-V, the caspase casade activation was detected by Wester blot, the effect of astragalus polysaccharids on expression and function of multidrug resistance protein (MRP) was detected by using real-time quantitative PCR and Western blot.
    Results: HL-60/A cells displayed obvious characteristics of resistance to doxorubicin, whose resistance were about 27 times that of its sensitive cell line HL-60. In addition, it was further found that astragalus polysaccharids could obviously increase the cell growth inhibition, induce cell apoptosis and caspase cascade activation, decrease the expression of MRP and increase the drug concentration in HL-60/A when combined with doxorubicin.
    Conclusion: Astragalus polysaccharids combined with doxorubicin can effectively overcome the drug resistance of HL-60/A. The mechanism may be associated with decreasing the expression of MRP, inhibiting drug efflux and increasing the intracellular drug concentration, then inducing HL-60/A cell apoptosis.

    Abstract Coronavirus disease 2019 (COVID-19), caused by the infection of a novel coronavirus [severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)], has become a pandemic. The infection has resulted in about one hundred million COVID-19 cases and millions of deaths. Although SARS-CoV-2 mainly spreads through the air and impairs the function of the respiratory system, it also attacks the gastrointestinal epithelial cells through the same receptor, angiotensin converting enzyme 2 receptor, which results in gastroenteric symptoms and potential fecal-oral transmission. Besides the infection of SARS-CoV-2, the treatments of COVID-19 also contribute to the gastroenteric manifestations due to the adverse drug reactions of anti-COVID-19 drugs. In this review, we update the clinical features, basic studies, and clinical practices of COVID-19-associated gastroenteric manifestations.

    Abstract Objective: To observe the cytotoxicity of indirubin derivative PHII-7 against human breast cancer MCF-7 cells and to study its primary mechanisms.
    Methods: The proliferation of MCF-7 cells was detected using MTT colorimetry. Annexin V/PI double staining was applied to detect the apoptosis rate of MCF-7 cells. The distribution of cell cycles was detected using PI staining and flow cytometry (FCM). The levels of reactive oxygen species (ROS) in MCF-7 cells were detected by DCFH-DA staining. The mRNA and protein levels of c-fos were detected using RT-PCR and Westem blot analysis.
    Results: PHII-7 at different concentrations inhibited the proliferation of MCF-7 cells in a concentration-dependent manner, with the inhibitory rate ranging from 43.13% to 90.90% (P < 0.05). The inhibition was strengthened along with increased concentrations. PHII-7 at different concentrations could induce the apoptosis of MCF-7 cells. The early apoptosis rate was 1.43% +/- 0.02%, 9.14% +/- 0.36%, and 45.79% +/- 8.46%, respectively with the action of 1.25, 2.50, and 5.00 micromol/L PHII-7, respectively, showing dose-dependent manner. FCM analysis found that the proportion of MCF-7 cells in the G0/G1 phase and the S phase decreased after treatment with PHII-7, and the ratio of MCF-7 cells in the G2/M phase obviously increased (P < 0.01). The intra-cellular ROS level was significantly elevated 2 h after pretreatment with PHII-7. The levels of the protooncogene c-fos mRNA and protein were down-regulated in a dose-dependent manner after action of PHII-7.
    Conclusions: PHII-7 exerted obvious in vitro cytotoxic effects on MCF-7 cells. Its mechanisms might be associated with arresting the cell cycle, regulating the redox equilibrium, and down-regulating the expression of the protooncogene.

    Abstract Since December 2019 to May 2020, coronavirus disease 2019 (COVID-19) has infected over 6 million people worldwide. Due to its sudden and rapid outbreak, effective treatment for COVID-19 is scarce. Based on national clinical trials of novel treatments, China, Italy, Germany, and other countries and organizations have published multiple guidelines for COVID-19 and advised many medicines, such as chloroquine and tocilizumab. In this paper, we summarize the pharmacotherapy for COVID-19 according to those guidelines, highlight updates of the pharmacotherapy guidelines, and review the efficacy and safety of the indicated anti-COVID-19 drugs.

    Abstract Objective: To evaluate whether ursolic acid can inhibit breast cancer resistance protein (BCRP)-mediated transport of rosuvastatin in vivo and in vitro.
    Methods: Firstly, we explored the pharmacokinetics of 5-fluorouracil (5-FU, a substrate of BCRP) in rats in the presence or absence of ursolic acid. Secondly, we studied the pharmacokinetics of rosuvastatin in rats in the presence or absence of ursolic acid or Ko143 (inhibitor of BCRP). Finially, the concentration-dependent transport of rosuvastatin and the inhibitory effects of ursolic acid and Ko143 were examined in Madin-Darby Canine Kidney (MDCK) 2-BCRP421CC (wild type) cells and MDCK2-BCRP421AA (mutant type) cells.
    Results: As a result, significant changes in pharmacokinetics parameters of 5-FU were observed in rats following pretreatment with ursolic acid. Both ursolic acid and Ko143 could significantly affect the pharmacokinetics of rosuvastatin. The rosuvastatin transport in the BCRP overexpressing system was increased in a concentration-dependent manner. However, there was no statistical difference in BCRP-mediated transport of rosuvastatin betweent the wild type cells and mutant cells. The same as Ko143, ursolic acid inhibited BCRP-mediated transport of rosuvastatin in vitro.
    Conclusion: Ursolic acid appears to be a potent modulator of BCRP that affects the pharmacokinetic of rosuvastatin in vivo and inhibits the transport of rosuvastatin in vitro.

    Abstract Background: Traumatic spinal cord injury (SCI) is a common disease in current clinical practice. Previous studies have reported that early surgical decompression was better to improve neurologic outcomes than that of late surgery. However, most of the studies set early surgery within 72 hours. Is urgent surgery within 24 hours superior to late surgery for SCI? It remains controversial.
    Objective: To determine whether neurologic outcomes of SCI in patients who underwent early surgery (<24 hours after injury) are better than those who underwent late surgery (≥ 24 hours after injury) by meta-analysis.
    Methods: Electronic databases such as PubMed, MEDLINE, EMBASE, and Cochrane library were selected to detect the potentially related trials up to June 2015 that compared the outcomes of early surgery (<24 hours after injury) versus late surgery (≥ 24 hours after injury) for the treatment of traumatic SCI. Data extraction and quality assessment were according to Cochrane Collaboration guidelines. Outcome evaluations were total motor score, neurologic improvement rate, length of hospital stay and intensive care unit (ICU) stay, complications, and mortality. Results were expressed as odds ratio (OR) for dichotomous outcomes and mean difference (MD) for continuous outcomes with 95% confidence interval (CI).
    Results: Nine articles comparing 2 cohorts that had early and late surgery for SCI were identified in this study. Statistically, there were significant differences between early and late surgery in total motor score (MD = 3.30, 95% CI = 0.82 ∼ 5.79, P < 0.01), neurologic improvement rate (OR = 1.66, 95% CI = 1.19 ∼ 2.31, P < 0.01), length of hospital stay (MD = -4.76, 95% CI = -9.19 ∼ -0.32, P = 0.04), and complications (OR = 0.61, 95% CI = 0.40 ∼ 0.91, P = 0.02). However, no significant differences were found between the 2 groups in mortality (OR = 1.39, 95% CI = 0.51 ∼ 3.75, P = 0.52). Two studies showed fewer ICU stays in the early-surgery group than in the late group.
    Conclusions: On the basis of this meta-analysis, urgent surgery within 24 hours for SCI significantly improved the neurologic outcomes compared with late surgery. It is suggested that urgent decompression within 24 hours is superior to delayed surgery for SCI.
